Considered by many mages to be the key to winning the Ascension War, Mount Qaf was the so-called Correspondence Point allowing access to all parts of the Tellurian, the perfect junction point for the flow of information, travellers, and power. The Ahl-i-Batin are credited with discovering it, and used it as the architectural keystone for the Web of Faith, a network through which information was transmitted at enormous speed during a period spanning the 8th century to the 13th century. The Web of Faith itself collapsed as a result of infighting, crusades, and the weakening of magical places of power, but its foundations remained, discovered by the Difference Engineers in the 1950s CE, thanks to whom it became the Digital Web. Access to Mount Qaf itself was lost at roughly the same time, but the Digital Web appears to continue to take advantage of its unique properties.
